Merge tag 'arc-uart-updates-for-2018.07-rc1' of git://git.denx.de/u-boot-arc Add support for DEBUG_UART on ARC devboards This required us to do 2 things: 1) Insert a call to debug_uart_init() in early boot code 2) Convert serial_arc to Kconfig Once both items above are done we just patched defconfigs.
